The authors describe the development of a double antibody radioimmunoassay specific for human secretory IgA (sIgA), and they report the results of measurements of serum sIgA concentrations in patients with chronic, nonalcoholic liver disease or carcinoma. Above-normal sIgA concentrations (greater than 25 micrograms/mL) were found in 22 of 38 sera from patients with chronic active liver disease and in 37 of 40 sera from patients with primary biliary cirrhosis. Markedly increased concentrations (greater than 118 micrograms/mL) were specific for primary biliary cirrhosis. Above-normal sIgA concentrations were found frequently in patients with colorectal (29/86, 34%), pancreatic (38/70, 54%), gastric (11/30, 37%), or mammary (6/46, 13%) carcinoma. An above-normal concentration of sIgA was more specific for hepatic metastases than an above-normal alkaline phosphatase activity in each type of carcinoma. The authors conclude that measurement of sIgA in serum is a useful diagnostic test in patients with chronic liver disease suspected of having primary biliary cirrhosis or in patients with carcinoma suspected of having hepatic metastases.

The records of 94 patients with a known diagnosis of extrahepatic cancer having liver scan, biochemical liver tests (alkaline phosphatase, SGOT, lactic dehydrogenase, and bilirubin levels, and subsequent liver biopsy within a six-week period were reviewed. The sensitivity, specificity, and accuracy of the scan and biochemical tests in the detection of metastatic liver disease were calculated. The most sensitive single examination was the group of biochemical liver tests. Liver scans performed in the presence of normal biochemical test results were insensitive when compared with the liver scan alone or the liver scan in the presence of abnormal biochemical test results. The specificity and accuracy of all tests and test combinations were statistically equivalent. Screening for hepatic metastases in patients with cancer is best accomplished with the more sensitive and less expensive group of biochemical liver tests, reserving the liver scan for those patients with abnormal biochemical test results.

Case report about death due to veno-occlusive liver disease following Dacarbazine treatment: 9 years after surgical treatment of malignant melanoma of the trunk a 68-years old patient developed lymph node metastases in the right axilla, which were removed immediately by surgical excision. One month before the patient had undergone surgical treatment of empyema of the gallbladder: Cholecystectomy and appendectomy were performed, postoperative recovery was uncomplicated. On account of the second lymph node metastasis within nine months adjuvant treatment with Dacarbazine was agreed and started one month later. After having performed the first course of treatment without any hints to intolerance the patient suddenly exhibited severe shock symptoms on the fourth day of the second course. Clinically residual myocardial infarct or pulmonary embolism were assumed, but could not be verified. The patient delivered increasing hepatomegaly. A massive increase in transaminase values was noted. Hemostasiologic changes with decreased Quick value occurred. The patient died of cerebral hemorrhage five days after beginning the second Dacarbazine cycle. Autopsy findings were severe liver cell necroses as well as liver vein thromboses, no metastases of melanoma could be found. Hepatotoxicity of Dacarbazine and the mechanism of liver vein thrombosis are discussed with special regards to possible hemostasiologic changes and sensibilisation due to Dacarbazine and/or previous liver cell damage.

During the past decade, one of the major changes in the field of oncology has been in the surgical approach to primary and secondary cancer of the liver. As a result of data and experience gained in liver transplantation programs and with the application of vascular surgical principles, resectability rates have been increased. The present rate of 32% has been achieved with an overall 30-day operative mortality rate of 9%. More sophisticated intraoperative and postoperative supports have been essential in achieving these results. The median operating time is now 4 3/4 hours in length. Complications are minimal. The median postoperative hospital stay is now 13 days. During the past decade, 436 patients with liver tumors were treated by the authors. It has become apparent in this experience and in that reported by others that an increasing number of patients with primary liver cancer or metastatic cancer in the liver can be cured by surgery with minimal operative risk. Adjuvant chemotherapy may increase the salvage rate. Current therapeutic results are best evaluated after staging of the liver disease: Stage I (no involvement of margins of resection, hepatic vascular structures or bile ducts; all gross disease removed): 85% three-year survival estimate, using the Kaplan-Meier method, for individuals with primary liver cancer; 71% for those with metastatic colorectal cancer. Stages II and III (regional or extrahepatic spread): 22% three-year survival for individuals with primary liver cancer but no survivors at two years with metastatic colorectal cancer. These data permit better selection of patients who are most likely to benefit from surgery.

In 3,600 patients evaluated with technetium-99m sulfur colloid for metastatic liver disease, 40 had equivocal scans due to a solitary defect in the interior margin of the right lobe. In these patients, the authors differentiated the gallbladder fossa from a metastatic focus using one of two new hepatobiliary agents: technetium-99m labeled pyridoxylideneglutamate and paraisopropylacetanilido iminodiacetic acid. In 31 patients, the focal defect filled with radioactive bile, showing that the solitary defect in the radiocolloid scan was a prominent gallbladder fossa. On laparoscopic biopsy, eight of nine patients whose focal defects were not due to the gallbladder were found to have metastatic disease. The ninth patient had carcinoma of the gallbladder. The need for laparoscopic biopsy was obviated in a majority (78%) of the patients by identifying the gallbladder fossa.

Circulating immune complexes have been described in viral hepatitis and primary biliary cirrhosis but their significance is unclear. Seventy-three patients with acute and chronic liver diseases were evaluated to determine the specificity of immune complex detection for a given liver disease. Immune complexes were measured by the fluid- and solid-phase Clq-binding assays. They were demonstrated frequently in all patients with liver disease, including those with viral hepatitis, alcoholic cirrhosis, chronic active and persistent hepatitis, drug-induced hepatitis and hepatic metastases. The presence of immune complexes was not specific for a given type of liver disease and did not correlate with hepatic dysfunction. We conclude that the detection of immune complexes is of no apparent diagnostic use in liver disease. Further evaluation of the antigen-antibody composition would be required to determine any pathogenic significance of the detected circulating immune complexes.

Receiver operator characteristic (ROC) techniques were used to determine relative importance of heterogeneity, bone marrow uptake, hepatomegaly, splenomegaly, and focal lesions in the scintigraphic diagnosis of cirrhosis, as well as to determine whether each of the criteria should be used as an identifier (high sensitivity) or as a discriminator (high specificity). Heterogeneity, splenomegaly, and bone marrow uptake were found to be good identifiers of hepatic disease. However, heterogeneity was found to be a poor discriminator for cirrhosis, splenomegaly showed some value as a discriminator, and bone marrow uptake was found to be a reliable discriminator for alcoholic liver disease. The presence of focal lesions was a good discriminator for metastatic disease, and was not specific for cirrhosis. Hepatomegaly also was not specific for cirrhosis. This method of analysis provides a relatively simple method for assembling a hierarchical guide to diagnostic criteria for the interpreting physician.

Obstetrician-gynecologists reviewed patient records of women delivering during January 1986-December 1992 to determine the maternal mortality rate and trends and the causes of maternal deaths in the maternity ward at the National University of Singapore. There were 26,173 deliveries and 9 maternal deaths (a maternal mortality rate of 22.9/100,000). The causes of maternal deaths were pulmonary embolism (underlying condition, systemic lupus erythematosus [SLE]), hemorrhage from multiple sites (thrombotic thrombocytopenia), acute exacerbation of SLE with interstitial pneumonitis, pulmonary fibrosis (systemic sclerosis), fulminant hepatitis (prior hepatitis and liver disease), and cerebral embolism (rheumatic heart disease with mitral valve replacement). There were also three incidental maternal deaths bringing the maternal mortality rate up to 34.4/1000. The incidental causes of death included septicemia from perforated peptic ulcer (uncontrolled thyrotoxicosis), multiple metastases from lung cancer, and suicide (family dispute over adoption of newborn). A cesarean section preceded 4 (44%) of the 9 maternal deaths. Two of these deaths were incidental maternal deaths. Cesarean section was related to two of the remaining six (33%) deaths. These findings show that traditional direct causes of maternal death (hemorrhage, sepsis, embolism, or hypertension) were not responsible for the maternal deaths at this tertiary facility. Instead, the women tended to have medical conditions that placed them at high risk of death regardless of pregnancy status.

During the period 1982-1990, 544 patients with clinical evidence of liver disease were admitted to King Fahd University Hospital, Al-Khobar, Saudi Arabia. Besides routine laboratory and sonographic investigations, all were subjected to either a needle liver biopsy, laparoscopy or a laparotomy. The tissue diagnoses were as follows: liver cirrhosis 17.3%, periportal fibrosis 14.3%, metastatic cancer 12.9%, primary hepatoma (hepatocellular carcinoma: HCC) 12.1%, hepatic granuloma 11.2%, chronic active hepatitis 7.7%, chronic persistent hepatitis 2.2%, fatty liver 7.2%, hydatid liver disease 4.6% and others 2.8%. In 7.7% the histology was normal. These results will be discussed and compared with results reported in local and international literature.

In ultrasonic imaging an adaptive two-dimensional filter (ATDF) can suppress randomly generated speckle using the ratio of the local variance to the local mean as the speckle recognition feature (R). The degree of smoothing depends on the difference between the recognition feature in the region to be filtered and the selected reference tissue. We have investigated the clinical application of ATDF for ultrasound B-mode images of liver abnormalities. Using the R values of normal liver as reference values, the ATDF images were displayed. Normal livers (n = 17, R = 2.19 +/- 0.14 M +/- SEM), fatty livers (N = 16, R = 1.89 +/- 0.15) and those with acute hepatitis (N = 10, R = 2.25 +/- 0.18) appeared smooth after application of the adaptive filter, but those diseases with higher R values, such as chronic hepatitis (N = 10, R = 3.04 +/- 0.30), cirrhosis (n = 16, R = 4.44 +/- 0.30), metastases (N = 16, R = 6.43 +/- 0.53) and hepatocellular carcinomas (N = 8, R = 7.92 +/- 0.85), were largely unsmoothed. In conclusion, ATDF allows differentiation of some forms of liver disease and may be helpful in the detection of microfocal echogenic textural lesions.
